担忧疫情蔓延美股“熔断”全球股市下跌(3)

"The radical measures have sent out a very worrying message to dealers, and that is why they are blindly dumping stocks."
“这些激进措施向交易商发出的信息非常令人担忧，因此他们在盲目抛售股票。”
In New York, steep falls as markets opened triggered another automatic halt to trading, which is meant to curb panic selling. Before last week, such halts, known as circuit breakers, had not been used in more than two decades.
纽约股市开盘后大幅下跌，再次引发“熔断”，即为了遏制恐慌性抛售而自动暂停交易。在上周出现“熔断”之前，美国股市已有20多年没有出现过这种情况。
【小知识：熔断机制是什么？】
首先，熔断机制的英文是circuit breaker mechanism，其中，circuit breaker在电工学里就是断路器的意思。当电路中出现短路时，断路器会立即断开电路，保护负载的安全。
The circuit breaker mechanism refers to measures adopted by stock exchanges to temporarily halt trading to avert panic selling after the stock index has fallen a certain percentage.
熔断机制是指股指下跌一定比例后，证券交易所采取暂停交易以避免恐慌性抛售的措施。
The circuit breaker mechanism aims to check abnormal prices wings.
熔断机制的目的是遏制交易价格异常波动。
业内人士表示，熔断机制可以给市场一个冷静期(cooling-off period)，让投资者充分消化市场信息(market information)，防止市场或某一产品非理性的大幅波动(fluctuations)，特别防止市场大幅下跌甚至发生股灾(stock market crash)，以维护市场的稳定。
